A handheld communication device may comprise a first housing and a second housing. The first housing may include a first keypad and a battery. The second housing may include a second keypad, at least one display, and a printed circuit board. The second housing may be rotatable relative to the first housing between an open configuration and a closed configuration. The second keypad may face in a substantially same direction as the first keypad in the open configuration, and the second keypad may face in a substantially opposite direction to the first keypad in the closed configuration.
